China is currently in an accelerated stage of population aging, and brain diseases pose a significant threat to the health of the elderly. " Preventing brain aging and maintaining brain health" has become a high-level goal of healthy aging. During the process of aging, the physiological and psychological states of elderly people change, making them prone to nervousness and exhaustion, which can disturb the brain spirit, damage the brain collaterals, and severely endanger brain health. Starting from the holistic view of cultivating both body and spirit in traditional Chinese medicine, based on the physical and mental characteristics of the elderly, this paper applies the concept and method of " relaxation and tranquility" in the protection of elderly brain health, focusing on maintaining relaxation and tranquility in both physical and mental aspects. Specific measures include emphasizing subjective consciousness, relaxing the heart and calming down; utilizing the daoyin method, relaxing the body and calming down, combining relaxation and tranquility, cultivating both body and spirit to prevent diseases and protect the brain, which enables the elderly to have a healthy mind and body, a sense of happiness and fulfillment, and to age gracefully. Simultaneously, advocating for tranquility is also called " respect" for relaxation, following nature to understand constant changes, and improving one′s ability to think positively in old age, in order to expand ideas for the protection of elderly brain health.

AIM: To analyze the clinical utility and value of the ultra-wide-field swept-source optical coherence tomography angiography(UWF-SS-OCTA)technique in changes of blood flow density and thickness in the central and peripheral regions of the retina and choroid in patients with nonproliferative diabetic retinopathy(NPDR)with or without diabetic kidney disease(DKD).METHODS: Cross-sectional study. Totally 50 cases(50 eyes)of diabetes mellitus(DM)that visited our hospital between June 2023 and June 2024 were included. They were divided into three groups: NPDR combined with DKD group(DKD group, n=20), NPDR without DKD group(NDKD group, n=20), and DM without retinopathy group(DM group, n=10, which served as control). In order to investigate the impact of DKD on ocular microangiopathy in NPDR patients, the retina and choroid within 24 mm×20 mm of the scan were separated into central and peripheral areas using the 3×3 nine-grid partition option that comes with UWF-SS-OCTA, and the parameters were then quantitatively assessed.RESULTS:The central and peripheral blood flow density of the choroidal capillary layer(CCP)was statistically significant between the DM group and the DKD group(t=3.93, P=0.0003; t=3.34, P=0.0016), and between the NDKD group and the DKD group(t=-3.06, P=0.003; t=-2.55, P=0.013), but there was no statistically significant difference between the DM group and the NDKD group(t=1.44, P=0.157; t=1.26, P=0.21). The mid-large choroidal vessel(MLCV)showed a progressive decline in central and peripheral blood flow density in the DM, NDKD, and DKD groups(F=13.74, 19.03, all P<0.0001). The DM, NDKD, and DKD groups saw a progressive decrease in central and peripheral choroidal thickness(CT; F=10.72, P=0.0001; F=13.12, P<0.001).CONCLUSION:CCP, MLCV, and CT can be used as visual indicators to identify impaired renal function in patients with NPDR. UWF-SS-OCTA can support the development of precise and noninvasive monitoring and treatment technology for diabetic ocular microangiopathy, while also offering a scientific foundation for the joint management of DR and DKD.

OBJECTIVE To systematically evaluate the efficacy and safety of different chemotherapy combination regimens for first-line treatment of metastatic colorectal cancer （mCRC）. METHODS PubMed， Cochrane Library， Embase and Web of Science were electronically searched to collect randomized controlled clinical trial （RCT） on first-line treatment for mCRC from January 1， 2000 to February 16， 2025. Two reviewers independently screened literature， extracted data and assessed the risk of bias of the included studies. Network meta-analysis was performed by using R4.4.3 and Stata 17.0 software. RESULTS A total of 28 RCTs， involving 16 intervention measures， were included. In terms of prolonging progression-free survival （PFS） and overall survival （OS）， FOLFOX （5-fluorouracil+oxaliplatin+calcium folinate regimen）+cetuximab had the highest probability of ranking first. In terms of improving objective response rate （ORR）， FOLFOXIRI （5-fluorouracil+oxaliplatin+irinotecan+calcium folinate regimen）+ bevacizumab and FOLFOX+bevacizumab+nivolumab had the highest probability of ranking first； in terms of the incidence of grade 3 or higher adverse reactions， FOLFOXIRI+panitumumab had the highest probability of ranking first； in subgroup analysis of KRAS wild-type patients， FOLFIRI （5-fluorouracil+irinotecan+calcium folinate regimen）+panitumumab and FOLFIRI+bevacizumab had the highest probability of ranking first in terms of prolonging PFS and OS， respectively； in terms of ORR， FOLFOXIRI+ cetuximab had the highest probability of ranking first. CONCLUSIONS In first-line treatment for mCRC， FOLFOX combined with targeted therapy has advantages in terms of efficacy and safety. However， individualized treatment strategies should be formulated based on the KRAS gene status and tumor location of patients.

AIM: To investigate the effect of intravitreal injection of recombinant tissue plasminogen activator(r-TPA)before pars plana vitrectomy(PPV)on surgical outcomes in patients with rupture of the globe(RG).METHODS: A retrospective study was conducted on 37 patients(37 eyes)with RG who underwent PPV 7-10 d after Stage Ⅰ suturing and stabilization at our hospital between April 2020 and November 2023. Based on whether an intravitreal r-TPA injection was administered 1 d before PPV, patients were divided into two groups, with 14 cases(14 eyes)in pre-operative r-TPA injection group, and 23 cases(23 eyes)in control group without pre-operative r-TPA injection. The intraoperative retinal reattachment rate, intraoperative silicone oil application, postoperative intraocular rebleeding, postoperative hypotony, and best-corrected visual acuity(BCVA)were compared between the two groups.RESULTS: The baseline characteristics were comparable between the two groups(P>0.05). Significant differences were found between the two groups in the intraoperative retinal reattachment rate, the volume of silicone oil injected, and the proportion of BCVA(all P<0.05). No statistically significant differences were observed in the intraoperative silicone oil tamponade rate, postoperative intraocular rebleeding, or postoperative hypotony rates(all P>0.05).CONCLUSION: RG patients who received an intravitreal r-TPA injection 1 d before PPV demonstrated significantly higher intraoperative retinal reattachment rates and better postoperative visual acuity outcomes.

OBJECTIVE: To observe the clinical effect of needle cauterization on vitiligo with deficiency cold and blood stasis. METHODS: A total of 62 patients of vitiligo with deficiency cold and blood stasis were randomly divided into an observation group and a control group, 31 cases each group.On the basis of 308 nm excimer light irradiation combined with ironing with Chinese medicine, the control group was treated with tacrolimus ointment for external use, twice a day; the observation group was treated with needle cauterization at vitiligo spots, once a week.Both groups were treated for 10 weeks. Before and after treatment, the area of vitiligo spot, TCM syndrome score, serum levels of inflammatory indexes (interleukin[IL]-6 and IL-17) were observed in the two groups, and the clinical effect was evaluated. RESULTS: After treatment, the areas of vitiligo spot, TCM syndrome scores and serum levels of IL-6, IL-17 were decreased compared with those before treatment in both groups (P<0.05), and the above indexes in the observation group were lower than those in the control group (P<0.05). The total effective rate in the observation group was 93.5% (29/31), which was higher than 77.4% (24/31) in the control group (P<0.05). CONCLUSION Needle cauterization could reduce the areas of vitiligo spot in patients of vitiligo with deficiency cold and blood stasis, improve the clinical symptoms, its mechanism may be related to the reduction of serum levels of inflammatory indexes.

Rice (Oryza sativa L.), as a thermophilic crop, is highly susceptible to cold stress during its growth process. Chilling injury at the plumule stage and seedling stage often affects the morphological development and leads to yield reduction of rice. The exploration and utilization of cold tolerance genes are among the most direct and effective approaches to address cold stress in rice. To identify quantitative trait loci (QTLs) associated with cold tolerance at plumule and seedling stages, in this study, we measured the seedling rates and survived seedling rates of the indica rice cultivar 'HZ', the japonica cultivar 'Nekken2', and their 120 recombinant inbred lines (RILs) under cold stress. A previously constructed high-density genetic linkage map was used for the mapping of the QTLs conferring cold tolerance at the plumule and seedling stages. A total of 4 QTLs for plumule-stage cold tolerance and 9 QTLs for seedling-stage cold tolerance were detected, with the maximum limit of detection reaching 5.20. Notably, a genetically overlapping QTL for both plumule and seedling stages was identified on chromosome 8, spanning a physical interval of 24 432 953-25 295 129 bp. Candidate genes within the detected QTL intervals were screened, and quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to analyze the gene expression during the plumule and seedling stages. The results revealed that LOC_Os03g06570, LOC_Os03g07100, LOC_Os06g08280, LOC_Os08g38440, LOC_Os08g39100, and LOC_Os08g39540 exhibited significantly differential expression between the parental lines. These genes were either significantly downregulated or upregulated under cold stress. Among them, the first three gene (LOC_Os03g06570, LOC_Os03g07100, and LOC_Os06g08280) were hypothesized to be key candidates regulating the cold tolerance of rice seedlings, while the latter three genes (LOC_Os08g38440, LOC_Os08g39100, and LOC_Os08g39540) were identified as comprehensive regulators of cold tolerance during both plumule and seedling stages. These findings lay a foundation for the fine mapping and cloning of cold tolerance genes at the plumule and seedling stages, providing valuable insights for breeding cold-tolerant rice varieties.

Objective To investigate the clinicopathological characteristics of radioactive Iodine-refrac-tory differentiated thyroid cancer(RAIR-DTC)to provide a clinical evidence for early prediction of the thyroid cancer patients with radioactive Iodine-refractory(RAIR).Methods The data of 84 patients with undergoing thyroidectomy and 131I therapy in PLA 960 hospital from January 2010 to December 2019 were retrospectively analyzed.Thirty-nine patients with diagnosed RAIR-DTC served as the study group and 45 cases of radioactive iodine-avid differentiated thyroid cancer(RAIA-DTC)served as the control group.The clinicopathological characteristics were compared between the two groups.The logistic regression was used to analyze the inde-pendent risk factors of RAIR-DTC,and the RAIR-DTC prediction model was established.Results Compared with the RAIA-DTC group,the RAIR-DTC group had more iodine treatment times,the proportions of the pa-tients with age ≥55 years old,total iodine therapeutic dose,distant metastasis,TNM stage Ⅳ,high-risk sub-types and focal calcification were higher,the tumor maximum diameter was greater,the number of lymph node metastases was more and the probability of Ⅱ,Ⅰ+Ⅱ and non-central lymph node metastases was higher(P＞0.05).The progression-free survival rate had statistical difference between the two groups(P＜0.05).The total survival rate had no statistical difference between the two groups(P＞0.05).The binary logistic re-gression analysis results showed that the distant metastasis,high-risk histological subtype and maximum tumor diameter ≥10.5 mm were the independent risk factors for RAIR-DTC.The obtained fitting equation logit(P)=-2.259+3.330X1+2.287X2+1.606X3,the ROC curve was used to calculate the truncation val-ue of the fitted equation as-0.312 5,when logit(P)＞-0.312 5,it might develop into RAIR-DTC.Conclusion The clinicopathological characteristics of the patients with differentiated thyroid cancer could ef-fectively predict RAIR.

Objective To investigate the application value of spectral computed tomography venography(CTV)in the display and staging of deep venous thrombosis(DVT)in the lower extremity.Methods Eighty-two patients with CTV were selected and ran-domly divided into group A(42 patients)and group B(40 patients).Group A:tube voltage 120 kVp.Group B:gemstone spectral ima-ging(GSI)mode,reconstruction of 50 keV and iodine(water)maps.The CT and standard deviation(SD)values of the veins were measured,signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)were calculated in 120 kVp images of group A and in 50 keV images of group B.Two observers scored the image quality of the 2 groups subjectively,and Kappa test was used to examine the con-sistency.Based on the duration from the occurrence of clinical symptoms,the DVTs were classified.The CT values and iodine con-centration(IC)of DVT were measured in the 120 kVp images of group A and in the iodine(water)maps of group B,respectively.The receiver operating characteristic(ROC)curve was drawn to compare the effectiveness of CT values and IC in diagnosing DVT staging.Results CT values,SNR,and CNR of veins in group B were higher than those in group A(P<0.05).The subjective scores of the two groups were consistent(Kappa=0.926-0.955,P<0.05).The score for the display of veins and thrombus clarity in group B was 5(4,5),which was better than the score of 4(3,4)in group A(P<0.05).The efficiency of IC in diagnosing DVT staging[area under the curve(AUC)=0.973]was better than that of CT values(AUC=0.891).Conclusion The spectral CTV can improve the contrast of lower extremity deep veins and the clarity of thrombus,and can provide more objective indicators for the diagnosis of thrombus staging,which is conducive to accurate clinical diagnosis and treatment.

ObjectiveTo use the maternal morbidity WOICE Tool（Chinese version）to investigate the maternal morbidity in Shanghai， and to examine the current situation and associated factors of adverse symptoms and impaired functioning in the third trimester and postpartum period. MethodsPregnant women who made their initial visit and established a medical record at a tertiary obstetrics and gynecology hospital in Shanghai from March to August 2021 were recruited and a baseline survey was completed. The prevalence of maternal morbidity was surveyed in the third trimester and first 6 weeks postpartum. ResultsSelf-reported adverse physical symptoms were observed in 89.8% of women in the third trimester and 86.1% in first 6 weeks postpartum. The prevalence rates of anxiety and depression were 4.1% and 6.2% in the third trimester， and 6.2% and 7.5% in first 6 weeks postpartum， respectively. The proportions of women reporting impaired functioning were 80.3% in the third trimester and 64.1% in first 6 weeks postpartum， respectively. Physical symptoms were associated with parity， education， the newborn’s health status， and risk of experiencing violence. Psychological symptoms were associated with age， household responsibilities， employment status， the newborn’s health status， pre-pregnancy body mass index （BMI）， and risk of experiencing violence. Functionality was associated with the type of registered residence， education level， household responsibilities， and risk of experiencing violence. ConclusionThe physical health status of pregnant and postpartum women in Shanghai is better than that in the middle-income regions abroad， with anxiety and depression at average levels compared to national statistics in China. Physical， psychological， and functional status are affected by multiple factors including personal， health， family， and work conditions. Preventive measures should be taken from various perspectives to mitigate adverse symptoms and impaired functioning， and to improve the positive experience of pregnancy and childbirth.

Nuclear factor kappa-B(NF-κB), an intricate nuclear transcription factor, is ubiquitously present within the myriad tissues and cells of the human corpus, engaging in a multiplicity of biological processes such as the development of the immune system, immune responses, inflammatory reactions, angiogenesis, and tumorigenesis. Its cardinal role in the pathogenesis of ocular diseases is increasingly illuminated by its prevalence. Owing to the unique architecture of the ocular globe, burgeoning studies have identified the excessive activation or dysregulation of the NF-κB signaling pathway as intimately associated with the progression of a multitude of ocular conditions, including, but not limited to, cataracts, dry eye syndrome, and glaucoma. The modulation of NF-κB activation, by targeting it, offers a potent mechanism for regulating ocular inflammation and mitigating disease progression, holding promise as a potential therapeutic strategy for ophthalmic disorders. An in-depth examination of the NF-κB signaling pathway's role in ocular diseases not only enriches our comprehension of the underlying mechanisms of these ailments, but also lays a crucial foundation for the innovation of new treatment modalities. Therefore, this article endeavors to provide a compendious review of the regulatory effects exerted by the NF-κB signaling pathway in ophthalmic conditions throughout recent years.
